It accommodates battery voltages of 12V and 24V, accepting a maximum input voltage of 100V from your solar panels at a standard temperature of 25°C. This voltage rating adjusts to 90V in colder conditions of -25°C, providing a safety margin for seasonal variations. With a discharge current handling capability of 20A, it is built for applications within dedicated solar controller setups. An optional BT-1 Bluetooth module is available, suggesting the potential for wireless monitoring, though specific functionality details are not provided.\n\n\u003ch2\u003eFeatures and Construction\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"BT-1 model solar panel charge controller for 12V and 24V battery systems.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US10\/629\/2025-10-02\/original-image\/2117903684910.webp\"\u003e\u003c\/div\u003e\nThis controller provides core regulation functions for off-grid or backup solar installations. Its specifications define clear operational limits for system integration.\n\u003ch3\u003eVoltage and Current Specifications\u003c\/h3\u003e\nThe controller supports dual battery system voltages, making it versatile for common 12V applications like caravans, boats, or small cabins, as well as 24V systems for slightly higher power needs. The 100V maximum photovoltaic (PV) input voltage at 25°C allows for connecting multiple panels in series to achieve a higher voltage, which can reduce current losses in longer cable runs. The specified drop to 90V at -25°C is a critical detail for installations in cold climates to prevent overvoltage damage from panels producing higher voltage in low temperatures.\n\u003ch3\u003eIntended Application and Model\u003c\/h3\u003e\nIdentified as model BT-1, this unit is described for use within 'solar controller systems,' indicating its role as a dedicated charge regulator. The listed 'application range' confirms its primary function is charge control, distinguishing it from inverters or other system components. The optional BT-1 Bluetooth module, listed under a 'Colour' option name, indicates a potential upgrade for remote monitoring via a smartphone app, a feature that adds convenience for checking system status without direct physical access to the unit.\n\n\u003ch2\u003eUses and Placement\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"BT-1 model solar panel charge controller for 12V and 24V battery systems.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US10\/629\/2025-10-02\/original-image\/3948628795689.webp\"\u003e\u003c\/div\u003e\nThis controller is suited for standalone solar power systems where regulating battery charge is essential.
